It had been over three years since Pikachu last tasted success at Sha Tin, but the seven-year-old made the most of Victor Wong Chun’s 10-pound claim to take out the Class Two Happy Valley Clubhouse Handicap on Sunday.

That was February 7, 2015 – winning over 1,400m with Maxime Guyon in the saddle – and since then Pikachu has done his best work at the city track.

But he took advantage of a lacklustre Class Two, Wong settling him midfield as Jolly Gene set a strong gallop before running over the top of his rivals in the straight.

Tony Cruz’s Hong Kong debutant Stimulation put in an eye-catching run to grab second, just ahead of Imperial Gallantry.

“He’s got a licence for next season and I certainly will be helping him. He’s riding a lot of horses for me today and I certainly will continue to support him because trainers like to see jockeys get vigorous on horses, especially weak Class Five horses – they need help and that’s exactly what he provides.”
